People who have led a sedentary lifestyle or those who smoke as a habit increase the chances for bulging disc.
Over time, spinal discs deteriorate and become more prone to damage. This indicates that developing a bulging or herniated disc becomes more likely with age. According to what starts to deteriorate first.
A disc may function normally if the nucleus pulposus, or the inner soft tissue, starts to deteriorate first.
However, if the inner nucleus pulposus escapes into the vertebral canal and presses on a nerve root or the spinal cord, this could happen if the outer supporting layer, the annulus fibrosus, begins to degenerate first.
